The present study reports the synthesis of supported zeolite with nanoscopic size on the SiC-based composite combining nanoscopic properties, i.e., SiC nanofibers, and macroscopic shaping, i.e., SiC foam with centimeters size. The SiC nanofibers have been obtained by the transformation of the carbon nanofibers by carburization in the presence of SiO vapour and then the zeolite was deposited on the SiC foam support. The different nature of the support results in different morphologies on zeolite crystal.
本研究报道了在具有纳米尺度特性（即碳化硅纳米纤维）和宏观形状（即厘米尺寸的碳化硅泡沫）的碳化硅基复合材料上合成具有纳米尺寸的负载型沸石。通过在SiO蒸汽存在下进行渗碳作用将碳纳米纤维转化而获得碳化硅纳米纤维，然后将沸石沉积在碳化硅泡沫载体上。载体性质的不同导致沸石晶体呈现出不同的形态。
